CHLORPHENIRAMINE
About
CHLORPHENIRAMINE belongs to the class of medication called 'sedating antihistamine' or 'anti-allergic' primarily used to treat symptoms of allergies such as itching nose/throat, runny nose, sneezing or red/itchy/watery eyes. An allergy occurs when foreign elements known as allergens attack and invade our body, thereby causing the release of histamine (a chemical messenger) that causes swelling, inflammation, redness, itchiness, watery nose, throat, and eyes.
CHLORPHENIRAMINE contains Chlorpheniramine, which works by blocking the action of histamine, a substance responsible for causing allergic reactions. It directly acts on the brain and relieves symptoms of allergies by preventing the release of histamine. It helps to provide relief from symptoms of allergy such as sneezing, running nose, watery eyes, itching, swelling, and congestion or stiffness.
Take CHLORPHENIRAMINE as prescribed by your doctor. You are advised to take CHLORPHENIRAMINE for as long as your doctor has prescribed it for you based on your medical condition. Some people may experience drowsiness, dizziness, constipation, blurred vision, restlessness, dry mouth, nose or throat. Most of these side effects of CHLORPHENIRAMINE do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.
Please tell your doctor if you are allergic to CHLORPHENIRAMINE or any other medicines. Please consult a doctor before taking CHLORPHENIRAMINE if you are pregnant or breastfeeding. Avoid using CHLORPHENIRAMINE if you have taken drugs such as linezolid, phenelzine, selegiline, rasagiline, isocarboxazid, tranylcypromine and methylene blue injection in the past 14 days. Drive only if alert, as CHLORPHENIRAMINE may cause blurred vision, drowsiness or dizziness. Avoid consumption of alcohol with CHLORPHENIRAMINE as it may increase the risk of adverse effects. Drink plenty of fluids while taking CHLORPHENIRAMINE to protect yourself from being dehydrated or overheated during exercise and in hot weather, as CHLORPHENIRAMINE decreases sweating and increases the risk of heatstroke.
